WHEEL-GLAEE?.

Specification of Letters Patent.

Application. filed February 17, 191?. Serial 2 50. 149,308.

To all whom it may concern Be it known that 1, JAMES E. Woonnnn, a citizen of the United States, residing at Vl aycross, in the county of Ware and State 5 of Georgia, have invented new and useful Improvements in- Wheel-Clamps, of which the following is a specification.

This invention relates to improvernents in means for clamoing the Wheel of a car.

or the like to a rail upon which the said wheel travels to permit of the raising of the axle and the removal of .the bearing brasses for repairs, etc, and the invention resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawing:

Figure l is a view illustrating the application of the improvement,

Fig. 2 is a perspective view of the improvement detached,

Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 2, and

Fig. i is a sectional view approximately on the line H of Fig. 3.

The application of the device is illustrated in Fig. 1 of the drawings, the improvement engaging between the wheel and the underface of the ball of the rail in the usual manner to lock the wheel to the rail and it may be here stated that while the improvement is illustrated as applied to one side oi the wheel the same may if desired be applied with equal ei'iiclency to the other side or face of the said wheel.

The improvement contemplates the em: ployment of a straight shank 1 having each end provided with lateral extensions 2 and 3 respectively, the said extensions both projecting beyond the said edge of the shank. The extension 2 preferably extends laterally over the opposite sides of the shank, as well. as beyond the referred to edge of the shank, whereby the same is enlarged and widened, the same being preferably rounded in plan. The rounded enlargement 2 is centrally formed with a threaded bore i, the threads of the said here engaging with a screw memher 5, the said screw upon the outer end thereof being formed with a head having a transverse opening through which is passed a slidable handle bar 6, the ends of said handle being enlarged as at 7, whereby to e5 prevent the removal of the handle from the head of the screw. The opposite end oi screw 5 is reduced to provide a extension 8 which has its outer a 1 with a continuous rounded which extension is beveled, itsinner end to the three. oi" t The flanged reduced eXtei on is be received in a suitable seal. or I provided upon the confronting o members 11 and 12 zroviding the jaw for the device. Bo l of these to have their confronting video. substantially rectangular whereby to receive the shank "l of the members to the opposite socket therein Within which. the of the screw is swiveled. prof outwardly extending lugs let that we ceived in openings 15 in the other of the jaw, and the last mentioned In 11 of the jaw is provided adjacent l opposite that receiving the lugs with a L- verse threaded orifice registering f similar orifice in the member 19 l ing in the threads of these orifices is member 15. The engaging face er the mov able jaw is rounded and is provided with transverse teeth 16. The lateral extension 3 projects a suitable distance b yond the outer end of the movable jaw is widened W or otherwise enlarged to FPO/Hi6 a it the upper edge of the said jaw being bevcled or inclined and being provi with transverse teeth 17. This law is adapted t underlie the head of the rail, while the .en gaging face of the movable jaw engageswith the wheel, as illustrated. in ii of the drawings, and as the operating handle for the screw is laterally adjustable with lation to the said screw it will he noted the" 95 the same may be manipulated to move t e movable jaw to and or away in tionarv jaw without inconvenience is operator.

The device in addition to being employed for locking the wheel to the rail ma he also used as a holding means for hot l s or as a conveying means for sai From the above description, tel u in N nection with the accompanying; d1: mg, simplicity of the device, as ivcll as the m vantages thereof will, it is thought. tectly apparent to those sir to which such invention appc a further detailed description. 9

Having thus described the invention, what I clain: is:

In a device for the purpose set forth, a substantially rectangular shank having its ends provided with lateral extensions projecting in the same direction, one of said extensions being widened and centrally provided with a threaded bore, a screw member engaging with the threads of the bore, a slidable handle for the screw, a reduced extension upon one'end of the screw, a flange formed. with the said extension, a slidable jaw upon the shank and comprising two similar members, said members having their confronting faces provided with a socket to receive the reduced extension of the sleeve,

and the flange thereon, said members having their confronting edges slotted to receive the shank, studs upon one of the members, the other member having openings to receive the studs, a removable element connecting the members, said jaw having its working face rounded and provided with transverse teeth, the second mentioned extension of the shank projecting beyond the movable jaw and having its end widened to provide a jaw, said head having its working face angular and formed with transverse teeth.

In testimony whereof I aflix my signature.
